Hi Keisuke,

We need more information to better help you.

For example:

• When you start the RDK_S3 program, do you see any issues on the teach pendant?
  
• What is the IP of your robot and the IP of the computer?
  
• Do you see the Fanuc robot web page when you type the IP of the robot on a browser from your computer?
  
• If not, did you properly establish the local connection with your robot?
  
• Can you ping the robot?
